Former Reds star McDermott, who was famed for his uncanny knack of hitting the target from midfield, is confident Henderson can achieve his target if he puts the hours in on the Melwood training pitches.
"I never scored many for Newcastle and if you look at my record you'll see I didn't get many in the first few seasons at Liverpool," McDermott, who netted 81 goals in 329 games for Liverpool, told LFC Weekly.
"I think it's definitely something you can learn to do. You adapt as you get older and you become a wiser footballer. You learn about what you can and can't do. I was a daft sod off the pitch but on it I wanted to win and cared about becoming a better player. I studied those around me and watched what they did. That helped me a lot.
"I began to realise what I needed to do to score more often. I was good at getting forward and knew that I could score more goals. The coaches at the club encouraged me to do it and that helped too. All of a sudden I was getting 15 to 20 goals a season.
"I think if Jordan works on that side of his game, there's no reason why he can't get double figures too. He's definitely capable of it. I think he has shown that with the goals he has scored for Sunderland."
